| resetToTop | | boolean resetToTop(Code) | | Screens should automatically reset to the top of the when
they are shown, except in cases where it is interrupted by
a system menu or an off-screen editor - in which case it
should be reshown exactly as it was.
|
| viewable | | int viewable(Code) | | An array which holds the scroll location and
the overall dimensions of the view being
shown in the parent Displayable's viewport
Note that the following is always true.
0 <= viewable[X] <= viewable[WIDTH] - viewport[WIDTH]
0 <= viewable[Y] <= viewable[HEIGHT] - viewport[HEIGHT]
|
| ScreenLFImpl | | ScreenLFImpl(Screen screen)(Code) | | Creates ScreenLF for the passed in screen.
Parameters:
screen - the Screen object associated with this look&feel |
| getMaxScroll | | protected int getMaxScroll()(Code) | | The maximum amount of scroll needed to see all the contents
get the maximum scroll amount |
| getScrollAmount | | protected int getScrollAmount()(Code) | | This is the number of pixels left from the previous "page"
when a page up or down occurs. The same value is used for line by
line scrolling
the number of pixels. |
| getVerticalScrollPosition | | public int getVerticalScrollPosition()(Code) | | Get the current vertical scroll position
int The vertical scroll position on a scale of 0-100 |
| getVerticalScrollProportion | | public int getVerticalScrollProportion()(Code) | | Get the current vertical scroll proportion
ing The vertical scroll proportion on a scale of 0-100 |
| lCallFreeze | | void lCallFreeze()(Code) | | Override DisplayableLFImpl.lCallFreeze() to set local variables.
|
| lCallHide | | void lCallHide()(Code) | | Override DisplayableLFImpl.lCallHide() to set local variables.
|
| lRequestPaintItem | | void lRequestPaintItem(Item item, int x, int y, int w, int h)(Code) | | Paint an Item contained in this Screen. The Item requests a paint
in its own coordinate space. Screen translates those coordinates
into the overall coordinate space and schedules the repaint
Parameters:
item - the Item requesting the repaint
Parameters:
x - the x-coordinate of the origin of the dirty region
Parameters:
y - the y-coordinate of the origin of the dirty region
Parameters:
w - the width of the dirty region
Parameters:
h - the height of the dirty region |
| setVerticalScroll | | boolean setVerticalScroll(int scrollPosition, int scrollProportion)(Code) | | Set the vertical scroll position and proportion
Parameters:
scrollPosition - The vertical scroll position to set on ascale of 0-100
Parameters:
scrollProportion - The vertical scroll proportion to set ona scale of 0-100. For example, if the viewportis 25 pixels high and the Displayable is 100pixels high, then the scroll proportion wouldbe 25, since only 25% of the Displayable canbe viewed at any one time. This proportionvalue can be used by implementations whichrender scrollbars to indicate scrollabilityto the user. |
| setVerticalScroll | | void setVerticalScroll()(Code) | | Set the vertical scroll indicators for this Screen
|
| setupScroll | | void setupScroll()(Code) | | all scroll actions should be handled through here.
|
| uCallPaint | | public void uCallPaint(Graphics g, Object target)(Code) | | Paint the contents of this Screen
Parameters:
g - the Graphics to paint to
Parameters:
target - the target Object of this repaint |
| uScrollAt | | protected void uScrollAt(int position)(Code) | | Perform a scrolling at the given position.
Parameters:
context - position |
| uScrollByLine | | protected void uScrollByLine(int dir)(Code) | | Perform a line scrolling in the given direction. This method will
attempt to scroll the view to show next/previous line.
Parameters:
dir - the direction of the flip, either DOWN or UP |
| uScrollViewport | | protected void uScrollViewport(int dir)(Code) | | Perform a page flip in the given direction. This method will
attempt to scroll the view to show as much of the next page
as possible.
Parameters:
dir - the direction of the flip, either DOWN or UP |
